Who is Sonar?

Sonar is pioneering the future of agent-centric software development. As a leader in AI code review and verification, we tackle a critical problem: ensuring that software generated by AI-assisted developers or autonomous agents is reliable, secure, and maintainable.

Integrating seamlessly with platforms like Claude Code, Codex, Cursor, GitHub Copilot, Gemini, and Devin, we assist over 75% of the Fortune 100 in building trusted, reliable, and compliant software. Our customers are 44% less likely to report an outage due to AI-generated code.

We believe that code verification is a crucial missing link in the Agent-Centric Development Cycle (AC/DC). Industry leaders such as Nvidia, ServiceNow, Booking.com, Goldman Sachs, AstraZeneca, and Ford Motor Company rely on us for independent, explainable, and consistent review and governance of their AI-generated code through products like:

• SonarQube: The world’s leading AI code review and verification platform.
• SonarQube Foundation Agent: Currently at the forefront of agentic software repair.
• SonarSweep & Sonar Context Augmentation: Providing the enterprise-grade context and constraints necessary for agents to be truly effective.

Our team operates from global hubs in Austin, Bochum, Dubai, Geneva, London, Singapore, Tokyo, and Washington D.C. We embody a mindset we refer to as CODE:

• Committed to our customers and community.
• Obsessed with quality.
• Deliberate in our decisions.
• Effective as one team.

With over $400 million in revenue and a track record of profitable, rapid growth, we are building the backbone of the AI software revolution. If you're eager to make an impact, wish to thrive in a fast-paced environment, and are ready to work at the forefront of AI, we want to hear from you.
